Inspired by advanced performance-forward sailcloth technology, X-Pac has become a carry community favorite due to its durability, waterproofness, and impressive strength-to-weight ratio. For this summer’s 2026 capsule collection, we constructed our all-day around-town sling in a stealth black X-Pac X42 shell and a covert coyote brown lining. In addition, we’ve added PU-coated YKK zippers to enhance CAS2's protection against the elements.
